COVER-HOLDER FOR BOOKS.

Specification of Letters Patent.

Patented Aug. 27, 1912.

AppIication filed March 1, 1909. Serial No. 480,525.

To all whom it may concern:

Be it known that I, RnINHoLo KRUMMING, of Milwaukee, Wisconsin, haveinvented a Cover-Holder for Books, of which the following is aspecification.

This invention relates to devices for holding books in open positionwithout manual assistance, and particularly those books which are thick,narrow or stiff-backed and tend strongly to close up of their ownaccord.

The invention has particular relation to books such as trade-cataloguesand other loose-leaf books which are used by solicitors and commercialtravelers to set their wares before prospective customers. Such booksare made with clamping-bars at the back for securing the leaves togetherand the leaves cannot therefore open flat as in an ordinary book, theinside edges thereof being held to gether in parallel relation at alltimes.

The invention consists in general in providing means, which may beseparate, or combined into a single bar, and are pivoted upon a memberwhich is secured to the book; said means being adapted to lie at rightangles to the axis. of the back upon the table or desk and thereby holdthe book upright, so that the back has no tendency to fall over to oneside or the other, which action results in causing that side which isuppermost to shut.

In the more improved forms of my invention, I provide a detachablemember which engages the back of the book and upon which the pivotedmeans are mounted. Moreover I may provide such detachable member with acertain adjustability whereby it is adapted to fit books of varioussizes.

My invention will best be understood from a description of a few of theconcrete forms which it may assume and which are shown in theaccompanying drawings, wherein,

Figure 1 is a perspective view of a looseleaf book having one of themost practical forms of my invention attached thereto; Fig. 2illustrates the same in position of use; Fig. 3 is an elevation of theback of a book showing the device attached thereto; Fig. t is an edgeview of the device separately; Fig. 5 is a transverse section throughthe holder on the plane 5; Figs. 6 and 7 are respectively a front andside elevation of a form of the holder which is especially adapted tobooks with telescoping covers; Fig. 8 is a perspective view of a bookshowing the same in use thereon; and Fig. 9

and the screw a tightened again. .member a, a may carry a cushion o in Ishows a simpler form of the holder permanently mounted on the cover of abook.

In these drawings each reference letter and numeral refers always to thesame part.

The holder shown in Figs. 1 to 5 inclusive comprises an adjustablebase-memberA, the same being in two parts a and of, which are connectedtogether by means of a fiatheaded clamping-screw a at a point near theend ofmember a which runs in a slot a in the member a while the extremeend of the member a is pressed up in the center to form a short rib awhich enters the slot 04 and thus forms a guide to hold the members aand a in line. screw (4 the member a may be shifted and secured in anydesired position corresponding to the length of the book. Each of themembers is provided at its end with a hook a, which is adapted to engageover the edge of the back Z) of any desired book B, and it will beunderstood that the screw a must be loosened in order to engage thehookwith the back and the parts then pushed together Each the form of a softrubber band which prevents scratching the back.

At an intermediate point of the length of the member a is mounted thebar C, being By loosening the.

pivoted upon a rivet c and provided at its ends with rubber-pads orcushions 0 It will be understood of course that when the member a ispushed in farther than the position shown in the drawing, the corresponding end of the bar C will be slightly lifted to enable the member a toslide under, the same as the rubber cushion a on the lefthand end asshown in Fig. 4.

When the book is not in use the bar C is kept folded up and superposedupon the member A, as shown in full lines in Fig. 1, but when the bookis to be opened and laid on the table, the bar C is turned into theposition shown in dotted lines in Fig. 1. the ends of the bar uponopposite sides of the pivot constituting a support for the book as shownin Fig. 2, holding the latter rigidly upright and thus preventing thebook from falling on one side or the other. Being so held the leavesthemselves have not sufficient resiliency to rise or to turn over fromone side to the other.

A simpler form of the device is shown in Figs. 6 to 8 inclusive, thisconsisting of a sheet-metal plate D bent into a U-shaped form and havinga bar pivoted upon a rivet c on one limb cl of the loop, while the othermember (Z is adapted to engage over the edge of one of the angular.clamping-bars of a book with telescoping back, as clearly shown in Fig.8. This formof holder operates in the same manner as the other, the barE corresponding to the bar 0' and being turned either at right angles orparallel to the back, according to whether in use or not. The ends ofthe bar E thus constitute supporting means. This form is of courseuseful only in the caseof 'telescoping backs, but the form of Fig. 1 canbe used with any kind of book.

In F ig. 9 is shown a form in which' the pivoted bar is made in theformbftwo wings permanently pivoted upon rivets f to the back 9 ofa bookG. Itwill be clear that when opened as shown in Fig. 9 these wings willperform the same function as V the cross-bar C in Fig. 2, and whenclosed they are out of the way so that. the book can be convenientlytransported.

While I have hereinabove shown the most improved form of my invention, Iwish it understood that not all of the features are essential thereto ornecessarily made in the exact form shown,but various changes andmodifications in the constructions as herein shown may be made withoutdeparting from the spirit of my invention, and I wish it understoodtherefore that the latter is not I adapted to engage over the ends of abook back from the outside, and means pivotally mounted on said barextendible on bot-h sides thereof.

3. A device for holding books in open position comprising, incombination, a basemember made in two parts, one of which has a slidingmotion with respect to the other, means for clamping said partstogether, each of said members having a hook on the end thereof adaptedto engage the ends of the back of a book, and means pivotally mounted onsaid member extendible on both sides thereof.

4. A device for holding books in open position comprising, incombination, a member made in two parts connected by a slot in one partand a clamping-screw in the other running in said slot whereby one ofsaid parts may have a longitudinal adjustment with respect to the other,each of said bars having a hook formed on its free end which is adaptedto engage over the back of a book, and means pivotally mounted on saidmember extendible on both sides thereof.

5'. A device for holding books inopen position comprislng two members,one of which is mounted on the back of the book and the other pivotallymounted on it and adapted to turn to a position at right angles theretoto extend on both sides thereof and having bosses projecting at an anglefrom the ends thereof for holding said members elevated from a table orother support vwhereby elevated mounting of the book is obtained. r Y I6. A device for holding books in open position comprising, ,incombination, two members, one of which 1s mounted on the back of thebook and the other pivotally mounted on it and adapted to turn at a fposit-ion at right angles to it to extend later-. v ally, and bossesprojectingat an angle from the ends thereof upon the underside forraising said member off of its support.

7. A device or holding books in open position, comprising a member 1ntwo parts having at their respective ends means for detachablyconnecting the same with the ends of a book back and a member pivotallymounted on and movable with one of said parts and movable into a planeat right angles to the length of the book to extend laterally on bothsides of the first-named member to form a support for the book.

8. A device for holding books in position, comprising a member havingone portion bent double over the other portion leaving I a narrow openspace between them adapted to fit over the back edge of a book, and asecond member pivotally mounted on the first to turn in a plane parallelto the plane of the back and to extend on both sides of the first-namedmember to form means to support the book upon opposite sides of saidback. f

In witness whereof, I have hereunto set my hand this twentieth day ofFebruary,
